Question

A liquid has a pH of 6.8. Write the formula for calculating the [H+] and then determine the value of [H+], making sure to include units with your answer.

Answer 1

Step-by-step explanation:

Formula to calculate pH is as follows.

pH =
`-log[H^(+)]`

It is given that pH is 6.8. Therefore, calculate the concentration of hydrogen ions as follows.

pH =
`-log[H^(+)]`

6.8 =
`-log[H^(+)]`

`[H^(+)]` = antilog (-6.8)

=
`1.58 * 10^(-7)` molarity

Thus, we can conclude that
`[H^(+)]` is
`1.58 * 10^(-7)` molarity.
